U73, or Hägerstalundstenen, is one more of Visäte's stones in Norra Järva. Written sources note its existence in the late 17th century, but it is likely to have stood in the same place as it does now since the mid 11th century when it was carved. The road it stands next to was the old district road and was in use from prehistoric times until it was replaced by Norrviksvägen in the 20th century.

The stone details the transfer of property - most likely land around Hägerstalund where the stone stands - by inheritance from a woman named Inga, whose sons died in Greece and who thereby reacquired ownership of the property, to Inga's brothers.​[1]

These landmarks are made in memory of Inga's sons. She came to inherit from them, but these brothers — Gerðarr and his brothers — came to inherit from her. They died in Greece.
